Skipper is right in a way. Fog the cylinders using old spark plugs , that way , in their thinking they can get you a new set in the spring. Fog it all. Injectors , cylinders, spray the motor down with a WD-40 type on the external parts. It works. Insulated garage or not, unless your taking all of us out for a ski run in December, there needs to be protection inside the engine too.
